Kobkul really went out of her way to make our stay at her guesthouse as comfortable as possible. She kept me informed when our room would be ready because she arrived early and on the last when we left late and not even together she made it possible for us to take a shower before departure.
The Thai breakfast that she brought in the morning was always tasty and awesome (tell her if you are vegetarian in advance) and her recommendations (floating market, busses) always precise and worth it.
We enjoyed our stay at her place very much and would definitely come back for a second time whenever in Bangkok.
